Indoor Air Quality Services in Greenville, SC
We identify the source of allergies, musty smells, dust, and humidity issues in your home and install the filtration, purification, and humidity control your system needs to fix them.
Greenville's Trusted Indoor Air Quality Team
Air Today Heating & Cooling has been working on indoor air quality issues across Greenville and the Upstate for over 45 years, and our local climate makes this one of the more challenging regions in the country to keep clean indoor air in. Spring brings some of the highest pollen counts on the East Coast. Summer brings the humidity that breeds mold and mildew in crawlspaces, ductwork, and tight modern homes.
When you call us out, we start by walking through your home and asking what your family is actually experiencing, whether it is allergy symptoms that get worse indoors, musty smells, excessive dust, condensation issues, or just stale air. From there, we identify the actual source of the problem and recommend the specific combination of filtration, purification, humidity control, or ventilation that will fix it.
We show up on time, keep the work area clean, and walk you through every product before we leave so you know how it works and how to maintain it. That approach has kept us in business for nearly five decades, and it is why homeowners across Greenville keep calling us back for indoor air quality, system upgrades, and everything else their HVAC throws at them.

Air Filtration Services
Filtration is the foundation of any indoor air quality plan and the first upgrade to make if you have not already.
Most homes ship with a basic 1-inch fiberglass filter rated MERV 4 to 6, which catches lint and large dust particles but lets pollen, pet dander, mold spores, and most allergens pass right through. Upgrading to a higher-MERV pleated filter or installing a 4-inch or 5-inch media cabinet captures significantly more without restricting airflow in your HVAC system. For homes in Greenville’s high-pollen seasons, this is often the single highest-impact change you can make.
Our air filtration services include:
- Inspection of your existing filter setup and HVAC system
- Recommendation of the right MERV rating for your equipment
- Upgrade to a higher-rated 1-inch filter or installation of a 4-inch or 5-inch media cabinet
- Sealing of the filter housing so that unfiltered air does not bypass the filter
- Setup of a replacement schedule that fits your home and pets
- Walk-through of how to change the filter yourself between visits
If your system cannot handle a higher MERV without restricting airflow, we will tell you that and recommend a different approach.
Air Purification Services
Purification goes beyond what filters can do and addresses the contaminants that pass through even high-MERV filtration. UV-C lights installed on your evaporator coil kill mold, mildew, bacteria, and some viruses on contact, which is especially valuable in Greenville where summer humidity makes coil mold a recurring problem. Whole-home in-duct purifiers like the REME HALO Zero and HALO-LED use active technology to reduce viruses, bacteria, mold spores, odors, and allergens at the source rather than waiting for them to circulate back to the filter.
Our air purification services include:
- Assessment of your home’s specific air quality concerns and HVAC system
- Recommendation between UV-C lights, in-duct purifiers, or both depending on what you need
- Installation of UV-C lights at the evaporator coil for mold and bacteria control
- Installation of whole-home in-duct purifiers like the REME HALO Zero or HALO-LED
- Wiring and integration with your existing HVAC equipment
- Walk-through of how the system works and what maintenance it needs
If a higher-quality filter will solve your problem without adding a purifier, we will tell you that first.
Humidity Control Services
Humidity control is the part of indoor air quality most homeowners do not realize they need until we explain it. Greenville’s summer humidity regularly pushes indoor levels above 60%, which creates the conditions for mold, dust mites, warped wood floors, and that stuffy feeling many homes get from May through September. Winter brings the opposite problem in tightly sealed homes, where heated air can drop indoor humidity below 30% and cause dry skin, sinus issues, static electricity, and damage to wood furniture and floors. Whole-home humidifiers and dehumidifiers solve both ends of the problem.
Our humidity control services include:
- Measurement of your home’s indoor humidity levels in summer and winter
- Recommendation of a whole-home humidifier, dehumidifier, or both
- Installation of equipment sized for your home’s square footage and HVAC system
- Integration with your existing thermostat or installation of a humidistat
- Setup of optimal humidity ranges for your home and family
- Full system test to confirm the equipment is hitting target humidity levels
If your humidity issues are caused by a duct leak or ventilation problem rather than equipment, we will diagnose that first before recommending any new system.
Indoor Air Quality Testing Service
Testing makes sense when you suspect a problem but cannot identify what is causing it, or when you want a baseline reading before adding filtration or purification equipment. We assess your home’s actual air quality, identify the specific pollutants causing your symptoms, and recommend the right combination of solutions instead of guessing. Common reasons to schedule a test include unexplained allergy or respiratory symptoms, recurring musty smells, visible mold in one area that may have spread, recent water damage, and homes purchased without prior IAQ history.
Our indoor air quality testing includes:
- Walkthrough assessment of your home and HVAC system
- Measurement of indoor humidity, temperature, and airflow at every register
- Inspection of ductwork, evaporator coil, and air handler for mold or contamination
- Visual inspection of crawlspaces and attics for moisture, mold, and pest issues
- Identification of the specific source of the problem
- Written report with recommended solutions ranked by impact and cost
If we find the issue is a leaky duct, dirty coil, or ventilation problem rather than something that needs a new IAQ product, we will tell you that and address the actual cause.
High Efficiency Air Filters
Air filters are essential components of your HVAC system that help trap dust, dirt, pollen, and other airborne particles. Our high-efficiency particulate air (HEPA) filters are designed to capture more airborne particles, resulting in cleaner and healthier air. These filters need to be replaced every few months, and our team can help you choose the right filter for your home.
REME HALO Zero Whole Home In-Duct Air Purifier
The REME HALO Zero is an advanced air purification system that uses active cleaning technology to target pollutants directly. This system is designed to reduce viruses, bacteria, mold spores, and odors right at the source. It works by releasing hydroperoxide plasma into the air, which actively seeks out and destroys pollutants. This system is especially beneficial for households with allergy or asthma sufferers.
HALO-LED Whole Home In-Duct Air Purifier
The HALO-LED is another powerful air purification system that can help improve the air quality in your home. This system uses an LED array that turns on and off with your blower, reducing power consumption and extending the product’s life. The HALO-LED also features automatic, self-cleaning ionizers that help reduce dust, dander, and pollen. It is designed to keep your home odor-free and comes with a 7-year limited warranty.

Frequently Asked Questions
The most common signs include allergy symptoms that get worse indoors, frequent headaches or fatigue, persistent musty or chemical smells, excessive dust on furniture even after cleaning, condensation or visible moisture on windows, dry skin, cracked wood floors or furniture, and visible mold or mildew growth in bathrooms, basements, or crawlspaces. If you are seeing several of these at once, it is worth scheduling an indoor air quality assessment to identify what is actually causing the problem.
MERV is a rating scale that measures how well a filter captures airborne particles, with ratings from 1 to 20. Most home HVAC systems work best with filters rated MERV 8 to 13, which catches dust, pollen, and pet dander without restricting airflow. HEPA filters are rated MERV 17 to 20 and capture nearly 100% of particles down to 0.3 microns. HEPA filters require a dedicated air handler in most cases because they restrict too much airflow for standard residential HVAC equipment.
Standard 1-inch disposable filters should be changed every one to three months, depending on filter quality, household pets, and how heavily the system runs. Pleated 4-inch and 5-inch filters typically last six months to a year. If you have pets, allergies, or run your system hard through Greenville’s pollen season, change them on the shorter end. A clogged filter forces your HVAC system to work harder, which costs you energy and shortens equipment life.
A whole-home air purifier can significantly reduce allergy and asthma triggers when it is matched to your home and HVAC system correctly. Purifiers reduce airborne pollen, dust, pet dander, mold spores, and viruses that pass through standard filters. The largest improvements usually come from combining a higher-MERV filter with a whole-home purifier or UV light. If allergies are severe, we may also recommend humidity control since dust mites and mold thrive in humid conditions.
Yes, when they are installed correctly. UV-C lights kill mold, mildew, bacteria, and some viruses by breaking down their DNA on contact. The most effective placement is on the evaporator coil, which stays damp during summer and is the most common spot for mold growth in Greenville homes. UV lights do not clean the air directly, so they work best in combination with high-quality filtration rather than as a standalone solution.
In most Greenville homes, a dehumidifier is the more important addition. The Upstate’s summer humidity regularly pushes indoor levels above 60%, which creates the conditions for mold, dust mites, and that stuffy feeling many homes get from May through September. Whole-home humidifiers can help during dry winter months, especially if you have hardwood floors or someone in the home suffers from dry skin or sinus issues. Some homes benefit from both, controlled by a single humidistat.
Yes, significantly. Dust, pet dander, pollen, and even mold can build up inside ducts over years of use, and every time your system runs, it pushes those contaminants back into the air you breathe. If you are noticing musty smells when the system kicks on, excessive dust around supply registers, or allergy symptoms that worsen indoors, your ducts are one of the first places to check.
